“The doors of your replica LaFerrari feature automatically opening and closing functions, powered by two dedicated motors.”





The Door Control Motors

NOTE: The Tank Bulkhead provided with this stage will not be needed until the next pack, so it can be safely stored away for now:

NOTE: I slightly changed the order of these steps from the instructions to make the process easier to follow.

Before we begin this stage, it is important that our steering system is aligned perfectly straight. Retrieve your Main Chassis from the previous stage and carefully set it upside down on a soft surface. Turn the front wheel hub assemblies to be parallel with the Chassis, as shown:

With the hubs centered, the rear gear of the Rack Shaft (from Stage 52) should be pointing straight up, as shown.

If you find these out of alignment, go back to the Step 2C of Stage 55 and realign your steering components:

Step 1

Retrieve your Steering Shaft and Rack Shaft Guard (Detail B) from Stage 52. With the flat end of the Steering Shaft (red arrow below) facing the passenger (right) side of the car, fit the the cog of the Steering Shaft on top of the gear of the Steering Rack. Then, cover it with the Shaft Guard (yellow arrow below), as shown:

For proper alignment of the Steering Wheel we will be installing in the next pack, it is vitally important that this flat edge of the Steering Shaft faces toward the passenger (right) side of the model:

When happy with the alignment, secure the Rack Guard to the Main Chassis with two (2) Type G screws.

Do not over-tighten these screws – the tighter they are, the harder it will be to operate the steering. This is also your friendly reminder to try using 3-in-One Oil on the threads of all screws going into metal parts:

Step 2

At the Right Door, slide the pin of a Door Piston Rod down inside the hole of the nearby Door Piston, as shown:

Fit the eyelet end of the Piston Rod over this short post of the Main Chassis, as shown:

Secure the Piston Rod to the Chassis with one (1) Type N screw.

Make sure that the screw is not too tight. This Piston Rod needs to be able to rotate about the post – it is a pivot point for the Door:

Repeat this step to install the second Piston Rod at the Left Door in the same way, using one (1) more Type N screw:

Step 3

Fit the left Door Motor Bracket to this matching location near the Windshield opening. There is a screw hole and a locating hole to properly orient this part, as shown. Secure the Bracket into place with one (1) Type G screw.

These Brackets are not the same, nor are they marked. Check the picture below to ensure you use the correct one here:

Repeat this process to secure the right Door Motor Bracket to the matching opposite side with one (1) more Type G screw, as shown:

Step 4

With the Doors of your LaFerrari in the fully closed position, lower the Right Door Motor (tagged ‘M2/R’) into this matching recess of the Main Chassis.

It was a known issue with the previous releases of this model that the motorized Doors can be troublesome. I feel that installing them gently and correctly is key to ensuring they have the best chance to operate properly. First, I recommend using some low-tack painter’s tape to temporarily hold both Doors closed as we work:

Then, we can slowly lower the Right Door Motor into the matching recess, as shown. It is an odd shape and we need to make sure we do not bend/break any of the attached wiring as we go:

An important area to be aware of is the wiring for the ‘limit switch’. This comes out the ‘top’ of the Motor inside the wheel well. Take precautions not to damage these components as you fit the Motor:

With the Motor fully seated and aligned to its mounting holes, firmly secure this Motor to the Chassis with four (4) Type G screws.

Don’t worry about routing the wires of these Motors just yet, we will do that later on:

In the same cautious way, fit the Left Door Motor to its matching recess. Secure it to the Chassis with four (4) more Type G screws, as shown:


I really took my time with this stage. These Door mechanisms are of a complex design and I truly want my Doors to work as expected!
